Jackshaft or parallel positioning combustion control is supported. Up to ten high-precision servos are networked to the controller, and 4-20 mA outputs are available to control VSDs for FD fan, FGR fan, ID fan or FW pump. Up to 14 combustion control points can be programmed for each output.
Combustion control system for a marine boiler
A combustion control system capable of accepting rapid load changes is shown in Figure . Two control elements are used, 'steam flow' and 'steam pressure'. The steam pressure signal is fed to a two-term controller and is compared with the desired value. Any deviation results in a signal to the summing relay.
Each boiler has a boiler master, which is an A/M/Bias station that handles the firing rate for that boiler. In AUTO, the boiler master receives the plant master output, biases it, and sends that % to the fuel and air flow controllers. In MANUAL, the boiler master output is adjusted by the operator.
Autoflame is a world leader in boiler/burner management systems for both commercial and industrial applications. Autoflame systems focus on fuel consumption, emissions, and labor costs. Systems feature touchscreen interfaces and rugged steel construction.
The boiler combustion control and monitoring system was installed on a 25 MMBtu/hr steam boiler located at the Watervliet Arsenal in New York. A one-year test conducted between February 2011 and March 2012 demonstrated a 4% fuel savings for typical utilization with natural gas.
